The following table lists many specialized symbols commonly used in modern mathematics, ordered by their introduction date. The table can also be ordered alphabetically by clicking on the relevant header title.
After the Roman conquest of Greece in the 1st century BC, Latin adopted the Greek letters Y and Z (or readopted, in the latter case) to write Greek loanwords, placing them at the end of the alphabet. An attempt by the emperor Claudius to introduce three additional letters Ↄ, Ⅎ, Ⱶ did not last.
